When meeting the man with the dynamite belt, Barney bends down and tells the man not to get up out of this chair, ending the segment. When the scene continues in the next segment, Barney is in the same position, but the paper that he is holding has switched from his left hand to his right hand.
When Fish bursts through the door at the beginning of the show, the squad room door doesn't close properly. After the camera switches to Nick and back, the door is closed.
Near the end of the show when Barney straps on the bomb, the phone rings and keeps ringing for a few seconds after Barney picks up the receiver.
In the final scene, where Fish and Barney are discussing the 40 square mile patch of garbage floating toward New York, a microphone shadow can be seen bobbing on the left window frame behind Barney.
